Huahana Huahana
ʻO ka waikawa Phosphorus i loko o ka wai kala ʻole, ʻike a me ka syrupy a i ʻole rhombic crystalline;ʻO kona helu hoʻoheheʻe he 42.35 ℃ a i ka wā e wela ai i ka 300 ℃ phosphorous acid e lilo ia i metaPhosphoric Acid;ʻO kona mānoanoa pili he 1.834 g/cm3; hiki ke hoʻoheheʻe ʻia ka waikawa phosphoric i ka wai a hoʻonā i ka ethanol;Hiki i ka waikawa Phosphate ke hoʻonāukiuki i ka ʻili o ke kanaka e hana ai i ka phlogosis a hoʻopau i ka pilikia o ke kino kanaka;Hōʻike ka phosphorus acid i ka corrosiveness i hoʻomehana ʻia i nā ipu seramika;Ua loaʻa i ka hydroscopicity ka waikawa phosphate.
Hoʻohana ʻia ka waikawa Phosporic:
Hiki ke hoʻohana ʻia ka ʻenehana Phosphoric Acid no ka hana ʻana i nā ʻano Phosphates, nā wai lapaʻau electrolyte a i ʻole nā wai lāʻau lapaʻau, refractory mortar me ka phosphoric acid a me ka coheretant inorganic.I ka ʻoihana hoʻopili ʻana i ka phosphoric acid i hoʻohana ʻia e like me ka uhi ʻana i ka ʻōpala no nā metala;Ma ke ʻano he mea hoʻoponopono acidity a me ka meaʻai meaʻai no ka mea hū meaʻai phosphoric acid hiki ke hoʻohana ʻia i nā mea ʻono, nā meaʻai canned a me nā mea inu māmā a me ka hoʻohana ʻia i loko o ka hale kīʻaha waina ma ke ʻano he kumu meaʻai no ka hū e pale ai i ka hana hou ʻana o nā hua bacteria ʻole.

Hoʻohana ʻia ka Phosphoric Acid no ka wehe ʻana i ka lepo mai nā ʻili metala Hoʻohana ʻia e like me ka hoʻololi ʻana i ka ʻōpala ma o ka hoʻopili pololei ʻana me ka hao ʻōpala, a i ʻole nā mea kila a me nā ʻili ʻē aʻe i ʻōpala.He mea kōkua ia i ka hoʻomaʻemaʻe ʻana i nā waihona minerala, nā ʻōpala nous sima a me nā ʻili wai paʻakikī.Hoʻohana ʻia e hoʻomaʻamaʻa i nā meaʻai a me nā mea inu e like me ka cola.He mea koʻikoʻi ka Phosphoric Acid i nā lāʻau lapaʻau e pale aku i ka nausea.Hoʻohui ʻia ka ʻakika Phosphoric me ka pauka zinc a hana i ka zinc phosphate, a he mea pono ia i ka sima niho manawa.I ka orthodontics, hoʻohana ʻia ka zinc ma ke ʻano he etching solution e kōkua ai i ka hoʻomaʻemaʻe a me ka hoʻomaʻemaʻe ʻana i ka ʻili o nā niho.Hoʻohana ʻia e like me ka hoʻoulu ʻana i ka lepo a puni kahi granule acidification i hana ʻia e hoʻomaikaʻi i ka hoʻohana ʻana i ka phosphorus i hoʻopili ʻia a loaʻa i ka rhizosphere.Ma muli o kona ʻano nitrogen (e like me ka ammonia), maikaʻi ia no nā mea kanu e koi ana i kēia mau meaʻai i kona wā mua.
